Generate an expression equivalent to: 5 + 6b + 12c + 10b - 4c - 2. in the simplest form of the equivalent expression, what is the coefficient of variable b?

The expression can be simplified by combining like terms:

5 + 6b + 10b + 12c - 4c - 2

Combining the terms containing b: (6b + 10b)

= 16b + 12c - 4c + 5 - 2

Simplifying further:

= 16b + 8c + 3

Therefore, the coefficient of variable b in the simplest form of the equivalent expression is 16.
